A population-based study comparing traumatic spinal cord injury and non-traumatic spinal cord injury using a national rehabilitation database

Prevalence of opioid use in adults with spinal cord injury: A systematic review and meta-analysis

OBJECTIVE

To determine the prevalence, reported harms and factors associated with opioid use among adults with spinal cord injury (SCI) living in the community.

STUDY DESIGN

Systematic review and meta-analysis.

METHODS

Comprehensive literature searches were conducted in PubMed (MEDLINE), EMBASE, CINAHL, Web of Science and Scopus for articles published between 2000 and 2023. Risk of bias was assessed using a prevalence-specific tool. Random-effects meta-analyses were conducted to pool prevalence data for any context of opioids. Sensitivity and subgroup analyses were also performed. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed, and the study protocol was registered via Prospero (CRD42022350768).

RESULTS

Of the 4969 potential studies, 38 were included in the review. Fifty-three percent of studies had a low risk of bias, with a high risk of bias in 5% of studies. The pooled prevalence for the 38 studies included in the meta-analysis (total cohort size of 50,473) across any opioid context was 39% (95% confidence interval [CI], 32-47). High heterogeneity was evident, with a prediction interval twice as wide as the 95% CI (prediction interval, 7-84%). Mean or median opioid dose was unreported in 95% of studies. Opioid dose and factors related to opioids were also rarely explored in the SCI populations.

CONCLUSIONS

Results should be interpreted with caution based on the high heterogeneity and imprecise pooled prevalence of opioids. Contextual details including pain, cohort-specific injury characteristics and opioid dosage were inconsistently reported, indicating a clear need for additional studies in a population at greater risk of experiencing opioid-related adverse effects.

Multidisciplinary rehabilitation following recreational nitrous oxide (N2O) misuse: evaluating service provision and rehabilitation outcomes in a cohort with serious disability

PURPOSE

Recreational nitrous oxide (N2O) misuse is increasing globally. Chronic misuse can cause neurological impairments that require rehabilitation, though literature characterising rehabilitation is limited. This study aimed to evaluate rehabilitation service provision for impairments resulting from N2O misuse.

METHODS

A retrospective audit of hospitalised patients referred for rehabilitation for N2O toxicity was conducted between 2015 and 2022 at a single metropolitan hospital. Data were collected via medical record audit and analysed via descriptive and non-parametric statistics.

RESULTS

16 eligible cases were identified, aged 18-43 years (50% female/male), with increasing case frequency. 12 cases received inpatient rehabilitation episodes for multifactorial sensorimotor, cognitive and psychosocial impairments. Cases articulated diverse rehabilitation goals and received intervention from a median of 6 clinical disciplines. All cases required assistance to mobilise or perform self-care activities on admission. Functional Independence Measure (FIM) scores significantly improved with rehabilitation (median FIM 84[75-93] to 117[112-123], p < .001). Despite gains in independence, all cases required referral for ongoing rehabilitation post-discharge.

CONCLUSIONS

Demand for inpatient rehabilitation for disabling N2O toxicity appears to be increasing. In this series, cases were young, exhibited serious impairments, and had multidisciplinary rehabilitation needs. Inpatient rehabilitation led to significant functional improvements, though ongoing disability was evident post-discharge.

Quality of life and subjective well-being comparison between traumatic, nontraumatic chronic spinal cord injury, and healthy individuals in China

Background

Differentiating between traumatic and non-traumatic spinal cord injuries (NT-SCI) is critical, as these classifications may significantly impact patients' health outcomes and overall well-being, potentially resulting in differences in treatment protocols and therapeutic efficacy.

Objective

This study aims to compare the quality of life (QoL) and satisfaction with life (SWL) among individuals with traumatic spinal cord injuries (T-SCI), NT-SCI, and the healthy population in China.

Method

A quantitative, cross-sectional survey was conducted between July and December 2020 in the Rehabilitation and Physiotherapy Department of Tongji Hospital, Hubei University of Science and Technology. The World Health Organization Quality of Life Brief Version (WHOQOL-BREF) and the Satisfaction with Life Scale (SWLS) were administered to evaluate QoL and subjective well-being (SWB). An independent t-test was performed to assess differences within the SCI population, while Pearson's correlation coefficient was utilized to explore relationships between the WHOQOL-BREF domains and the SWLS. Multiple linear regression analysis was applied to identify key determinants influencing World Health Organization Quality of Life (WHOQOL) domain scores and overall SWLS score.

Result

Participants with NT-SCI exhibited significant differences in overall health as measured by the WHOQOL-BREF domains compared to those with T-SCI (p < 0.05). Both the NT-SCI and T-SCI groups demonstrated lower mean scores across all four WHOQOL-BREF domains compared to healthy individuals. No significant differences were observed between the NT-SCI and T-SCI groups in the SWLS, although both groups scored lower than the healthy population. Additionally, SWB was moderately positively correlated with QoL (p < 0.01). Collectively, the predictor variables explained 22.28% of the variance in physical health, 6.43% in psychological health, 28.67% in social health, and 25.68% in environmental health. Furthermore, the independent variables accounted for approximately 22.67% of the variance in the SWLS.

Conclusions

Individuals with NT-SCI experience significantly worse overall health outcomes compared to those with T-SCI, although both groups report QoL and life satisfaction than healthy individuals. No significant differences in life satisfaction were found between two groups. Additionally, SWB shows a moderate positive correlation with QoL, highlighting the close relationship between mental and physical health in SCI populations.

Unveiling the mosaic: comparing demographics and outcomes in traumatic vs. non-traumatic spinal cord injuries

BACKGROUND

This study analyzed the percentage of patients with nontraumatic spinal cord injury (SCI) which is increasing with the increase of population age. However, little is known about the effect of the etiology of SCI on the outcome of these subjects.

AIM

The aim of this study was to investigate functional and neurological outcomes in patients with traumatic and nontraumatic spinal cord lesions, with a focus on factors influencing rehabilitation outcomes.

DESIGN

The design of this study was that of a retrospective analysis of prospectively recorded data.

SETTING

The setting of this analysis was a single Spinal Unit in Italy.

POPULATION

The population included 1080 subjects, of which 599 (55%) had injuries of traumatic origin and 481 (45%) had nontraumatic injuries.

METHODS

International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI), the Spinal Cord Independence Measure (SCIM) and the Walking Index for Spinal Cord Injury (WISCI) were utilized as measurement tools. Multivariate (backwards selection, P=0.20) logistic regression was used to assess the associations of "complication during hospitalization," "bowel management autonomy," "spontaneous micturition," "home destination" and "neurological improvement" with the following variables: etiology, age, sex, lesion level and severity and length of stay. Multivariate (backwards selection, P=0.20) negative binomial regression was used to assess the relative risks of higher SCIM and WISCI Scores at discharge after adjusting for the abovementioned variables.

RESULTS

Our work highlighted several significant differences between the traumatic and nontraumatic groups (including age, sex, lesion severity, and time from lesion onset to admission). Both groups exhibited comparable improvements in neurological and functional status, although some data were in favor of subjects with traumatic lesions. However, the regression analyses demonstrated that the main factors impacting the neurological and functional status at discharge were age, lesion level and severity, rather than the etiology of the lesion.

CONCLUSIONS

Our study provides valuable insights into the rehabilitation trajectories of traumatic and nontraumatic spinal cord injuries and demonstrates that the cause of SCI has no impact on rehabilitation outcomes.

CLINICAL REHABILITATION IMPACT

An understanding of neurological and functional recovery after spinal cord lesions is essential for answering patients' questions about their potential functional capabilities. It also assists in determining the necessary resources for inpatient rehabilitation and post discharge care. Moreover, the possession of a thorough grasp of the course and factors influencing the natural recovery of a spinal cord lesion is now a scientific necessity and is crucial for assessing the efficacy of new pharmacological and rehabilitative methods.

Global incidence and characteristics of spinal cord injury since 2000-2021: a systematic review and meta-analysis

BACKGROUND

This study employs systematic review and meta-analysis to explore the incidence and characteristics of spinal cord injury (SCI) between 2000 and 2021, aiming to provide the most recent and comprehensive data support for the prevention, diagnosis, treatment, and care of SCI.

METHODS

Systematic searches were conducted on epidemiological studies of SCI published between January 1, 2000, and March 29, 2024. Meta-analysis, subgroup analysis, meta-regression, publication bias detection, and literature quality assessment were extensively utilized.

RESULTS

The pooled results from 229 studies indicated that the overall incidence rate of SCI was 23.77 (95% CI, 21.50-26.15) per million people, with traumatic spinal cord injuries (TSCI) at a rate of 26.48 (95% CI, 24.15-28.93) per million people, and non-traumatic spinal cord injuries (NTSCI) at a rate of 17.93 (95% CI, 13.30-23.26) per million people. The incidence of TSCI exhibited a marked age-related increase and was significantly higher in community settings compared to hospital and database sources. Males experienced TSCI at a rate 3.2 times higher than females. Between 2000 and 2021, the incidence of TSCI remained consistently high, between 20 and 45 per million people, whereas NTSCI incidence has seen a steady rise since 2007, stabilizing at a high rate of 25-35 per million people. Additionally, the incidence of TSCI in developing countries was notably higher than that in developed countries. There were significant differences in the causes of injury, severity, injury segments, gender, and age distribution among the TSCI and NTSCI populations, but the proportion of male patients was much higher than that of female patients. Moreover, study quality, country type, and SCI type contributed to the heterogeneity in the meta-analysis.

CONCLUSIONS

The incidence rates of different types of SCI remain high, and the demographic distribution of SCI patients is changing, indicating a serious disease burden on healthcare systems and affected populations. These findings underscore the necessity of adopting targeted preventive, therapeutic, and rehabilitative measures based on the incidence and characteristics of SCI.

Experiences of people with non-traumatic spinal cord injuries returning home after inpatient rehabilitation

PURPOSE

The aim of this study was to explore the experience of people with non-traumatic spinal cord injuries who have recently returned home from inpatient rehabilitation.

METHODS

Semi-structured interviews were conducted with seven adults with non-traumatic spinal cord injuries who had been discharged from inpatient rehabilitation from an Australian rehabilitation hospital, within the last two years.

RESULTS

Three themes were identified: the practicalities of coming home; adjusting to "my altered home life"; pursuing recovery. When people felt prepared by their rehabilitation service, and had appropriate support from others, they had a more positive adjustment experience, although not one without challenges. Due to less independence and inability to participate in meaningful life roles, participants experienced a sense of lost or changed identity. Maintaining hope for physical recovery was very important and motivated participants to actively engage in rehabilitation efforts.

CONCLUSIONS

This study adds to the knowledge regarding the lived experience of people with non-traumatic spinal cord injury transitioning from rehabilitation to home. Facilitators for successful rehabilitation discharge included ensuring community services contacted patients immediately after they left hospital, and providing support for carers. Health care workers can positively influence the adjustment process of people with NTSCI by facilitating re-engagement in meaningful roles.IMPLICATIONS FOR REHABILITATIONThe transition home from inpatient rehabilitation after non-traumatic spinal cord injury (NTSCI) is facilitated by early discharge planning and follow-up from services after discharge.Establishing routines helped participants adjust to their new circumstances.The emotional and practical support of carers is vital for successful adjustment to living in the community with an NTSCI.Health care workers can positively influence the adjustment process of people with NTSCI by facilitating their re-engagement in meaningful roles.

Rehabilitation: Neurogenic Bone Loss after Spinal Cord Injury

Osteoporosis is a common skeletal disorder which can severely limit one's ability to complete daily tasks due to the increased risk of bone fractures, reducing quality of life. Spinal cord injury (SCI) can also result in osteoporosis and sarcopenia. Most individuals experience sarcopenia and osteoporosis due to advancing age; however, individuals with SCI experience more rapid and debilitating levels of muscle and bone loss due to neurogenic factors, musculoskeletal disuse, and cellular/molecular events. Thus, preserving and maintaining bone mass after SCI is crucial to decreasing the risk of fragility and fracture in vulnerable SCI populations. Recent studies have provided an improved understanding of the pathophysiology and risk factors related to musculoskeletal loss after SCI. Pharmacological and non-pharmacological therapies have also provided for the reduction in or elimination of neurogenic bone loss after SCI. This review article will discuss the pathophysiology and risk factors of muscle and bone loss after SCI, including the mechanisms that may lead to muscle and bone loss after SCI. This review will also focus on current and future pharmacological and non-pharmacological therapies for reducing or eliminating neurogenic bone loss following SCI.

Prevalence and Determinants of Pain in Spinal Cord Injury During Initial Inpatient Rehabilitation: Data From the Dutch Spinal Cord Injury Database

OBJECTIVE

To describe the prevalence and characteristics of spinal cord injury (SCI)-related pain during initial inpatient rehabilitation and to investigate relationships with demographic and lesion characteristics.

DESIGN

Cohort during inpatient rehabilitation.

SETTING

Eight specialized SCI rehabilitation centers in the Netherlands.

PARTICIPANTS

Patients with newly acquired SCI admitted for inpatient rehabilitation between November 2013 and August 2019 (N=1432).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Presence of pain at admission and discharge. Logistic regression analyses were used to study the prevalence of pain related to sex, age, etiology, completeness, and level of injury.

RESULTS

Data from 1432 patients were available. Of these patients 64.6% were male, mean age was 56.8 years, 59.9% had a nontraumatic SCI, 63.9% were classified as American Spinal Cord Injury Association Impairment Scale (AIS) D and 56.5% had paraplegia. Prevalence of pain was 61.2% at admission (40.6% nociceptive pain [NocP], 30.2% neuropathic pain [NeuP], 5.4% other pain) and 51.5% at discharge (26.0% NocP, 31.4% NeuP, 5.7% other pain). Having NocP at admission was associated with traumatic SCI. AIS B had a lower risk of NocP than AIS D at admission. Having NocP at discharge was associated with female sex and traumatic SCI. AIS C had a lower risk of NocP at discharge than AIS D. Having NeuP at admission was associated with female sex. Having NeuP at discharge was associated with female sex, age younger than 65 years vs age older than 75 years and tetraplegia.

CONCLUSIONS

SCI-related pain is highly prevalent during inpatient rehabilitation. Prevalence of NocP decreased during inpatient rehabilitation, and prevalence of NeuP stayed the same. Different patient and lesion characteristics were related to the presence of SCI-related pain. Healthcare professionals should be aware of these differences in screening patients on presence and development of pain during inpatient rehabilitation.

Epidemiology of non-traumatic spinal cord injury in Ireland - a prospective population-based study

Objective: To carry out a study of non-traumatic spinal cord injury (NTSCI) epidemiology in IrelandDesign: Prospective study of all new incident cases of NTSCI during 2017Setting: Republic of IrelandParticipants: All persons with a newly acquired NTSCIInterventions: NoneOutcome measures: Crude and age/sex specific incidences; ISCoS core dataset and non-traumatic dataset; population denominator was 2016 national census figures, adjusted to 2017.Results: Overall crude incidence of NTSCI in the Republic of Ireland in 2017 was 26.9 per million per year. Mean age at onset was 56.6 (SD 17.7) years. Females accounted for 51.2% of cases. Most frequent grade of ASIA impairment scale (AIS) was AIS D. Most common etiology was degenerate conditions (48.8%) followed by neoplastic (26.4%). The most common pattern of onset (51.2%) was lengthy (greater than one month).Conclusions: Incidence of NTSCI is more than double that for traumatic SCI in the Republic of Ireland. This suggests that the delivery of rehabilitation services to patients with spinal cord injuries requires prompt review and expansion.

Traumatic and non-traumatic spinal cord injury: Demographic characteristics, neurological and functional outcomes. A 7-year single centre experience

Objective

The aim of this study is to evaluate demographic and clinical characteristics of a population affected by traumatic and non-traumatic spinal cord injury (SCI) and to analyze functional outcomes after rehabilitation.

Methods

This study involved 112 SCI patients (75 male and 37 female) admitted at the Neurorehabilitation Unit of the University Hospital of Messina. The neurological outcomes were evaluated according to the American Spinal Injury Association Impairment Scale (AIS) and by using length of stay, Functional Independence Measure (FIM) and Barthel Index (BI).

Results

NT-SCI patients were significantly older, numerous (75,89%) and affected by greater lesions when admitted, than T-SCI ones. Most of lesions were incomplete (93%) and associated with paraplegia (71%). FIM and BI outcomes are similar in both groups, even if T-SCI patients showed greater improvement when discharged. No significant differences were found in the length of stay. The most common complication in non-traumatic SCI group was urinary tract infection and this was observed in 25 patients (29,41%). Linear regression models explained 26% of the variance of LOS and 38% of the variance of functional outcome. Functional status on admission was the strongest determinant of LOS and completeness of the lesion was the strongest determinant of functional outcome. Etiology (traumatic versus non-traumatic) was a weak independent determinant of LOS but was not an independent determinant of functional outcome.

Conclusion

SCI patient's rehabilitation should be carried out by taking into account etiology of the injury. It is important to consider this information while developing the targets and planning of the rehabilitation program. In particular, older age negatively influence the degree of disability on admission and the entity of functional recovery in both populations. Non-traumatic lesions could have minor benefits after rehabilitation therapy if compared with traumatic ones.

Epidemiological changes in traumatic spinal cord injuries for the last 30 years (1990-2019) in South Korea

STUDY DESIGN

Retrospective descriptive study.

OBJECTIVES

To identify the characteristics of and epidemiological trends in traumatic spinal cord injuries (TSCIs) in Korea from 1990 to 2019.

SETTING

National Rehabilitation Center affiliated with the Ministry of Health and Welfare in Korea.

METHODS

The medical records of 3395 individuals with TSCIs were retrospectively reviewed. Three groups were formed based on onset period (1990-1999, 2000-2009, and 2010-2019) and six groups based on age (≤15, 16-30, 31-45, 46-60, 61-75, and ≥76 years). Pearson's chi-square and analysis of variance tests were used for statistical analysis.

RESULTS

From 1990 to 2019, the mean age (standard deviation, [SD]) at the time of injury increased from 32.4 (SD = 12.4) years in the 1990s to 47.1 (SD = 16.2) years in the 2010s (F = 222.317 p = <0.001). Land transport and falls were the most common causes of TSCIs. The number of injuries from land transport gradually decreased, while that from falls increased (24.9% in 1990s to 46.3% in 2010s [χ² = 134.415 p < 0.001]). In the >60 years group, falls were the most common cause of injury, which resulted in 42.9% TSCIs in the 1990s to 59.1% in the 2010s (χ²= 10.398, p > 0.05). Tetraplegia (n = 769, 58.6%) was more common than paraplegia; incomplete tetraplegia (entire population: =564, 43%; >60 years group: n = 186, 43%) was the highest in the 2010s.

CONCLUSIONS

Falls have been the most common cause of TSCIs after 2010s. Implementing national education and campaigns for preventing falls is important to reduce/prevent TSCIs caused by falls in the aged population.

Epidemiologic changes in nontraumatic spinal cord injury for the last 30 years (1990-2019) in South Korea

STUDY DESIGN

Retrospective descriptive study.

OBJECTIVES

To summarize epidemiologic data on nontraumatic spinal cord injury (NTSCI) for the last 30 years and compare these findings to data from individuals with traumatic spinal cord injury (TSCI).

SETTING

National Rehabilitation Center affiliated with the Ministry of Health and Welfare in Korea.

METHODS

The medical records of 948 individuals with NTSCIs were retrospectively reviewed. Three groups were created based on onset period (1990-1999, 2000-2009, 2010-2019) and six groups based on age (≤15, 16-30, 31-45, 46-60, 61-75, and ≥76 years). Pearson's chi-square and analysis of variance tests were used for statistical analysis.

RESULTS

The male-to-female ratio was 1.30:1 for NTSCI individuals and 3.47:1 for TSCI individuals. The mean age (standard deviation [SD]) at the time of injury increased from 38.7 (SD = 18.1) years in the 1990s to 55.5 (SD = 16.6) years in the 2010s (F = 44.597, p ≤ 0.001). Vertebral column degenerative disorder was the primary cause of injury in 28.9% of the cases, and the most common neurologic level was T12-L2. Paraplegia occurred in 74.6% of cases, and tetraplegia in 25.4% of cases. The proportion of NTSCI individuals increased from 11.2% to 29.3% during the observation period.

CONCLUSIONS

The proportion of NTSCI among total spinal cord injuries has increased in Korea over the last 30 years (1990-2019). Compared to individuals with TSCI, those with NTSCI had a higher age at onset, with different male-to-female ratios. Our study is the most comprehensive investigation of NTSCI in Korea, and our findings can inform research directions and medical guidelines.

Dynamic body-weight support to boost rehabilitation outcomes in patients with non-traumatic spinal cord injury: an observational study

Background

Dynamic body-weight support (DBWS) may play an important role in rehabilitation outcomes, but the potential benefit among disease-specific populations is unclear. In this study, we hypothesize that overground therapy with DBWS during inpatient rehabilitation yields greater functional improvement than standard-of-care in adults with non-traumatic spinal cord injury (NT-SCI).

Methods

This retrospective cohort study included individuals diagnosed with NT-SCI and undergoing inpatient rehabilitation. All participants were recruited at a freestanding inpatient rehabilitation hospital. Individuals who trained with DBWS for at least three sessions were allocated to the experimental group. Participants in the historical control group received standard-of-care (i.e., no DBWS). The primary outcome was change in the Functional Independence Measure scores (FIM_gain).

Results

During an inpatient rehabilitation course, participants in the experimental group (n = 11), achieved a mean (SD) FIM_gain of 48 (11) points. For the historical control group (n = 11), participants achieved a mean (SD) FIM_gain of 36 (12) points. From admission to discharge, both groups demonstrated a statistically significant FIM_gain. Between groups analysis revealed no significant difference in FIM_gain (p = 0.022; 95% CI 2.0–22) after a post hoc correction for multiple comparisons. In a secondary subscore analysis, the experimental group achieved significantly higher gains in sphincter control (p = 0.011: 95% CI 0.83–5.72) with a large effect size (Cohen’s d 1.19). Locomotion subscores were not significantly different (p = 0.026; 95% CI 0.37–5.3) nor were the remaining subscores in self-care, mobility, cognition, and social cognition.

Conclusions

This is the first study to explore the impact of overground therapy with DBWS on inpatient rehabilitation outcomes for persons with NT-SCI. Overground therapy with DBWS appears to significantly improve functional gains in sphincter control compared to the standard-of-care. Gains achieved in locomotion, mobility, cognition, and social cognition did not meet significance. Findings from the present study will benefit from future large prospective and randomized studies.

Incidence of Acquired Nontraumatic Spinal Cord Injury in Finland: A 4-Year Prospective Multicenter Study

OBJECTIVES

To evaluate the incidence and epidemiologic characteristics of acquired nontraumatic spinal cord injury (NTSCI) in Finland.

DESIGN

Prospective 4-year epidemiologic multicenter study.

SETTING

Two of the 3 spinal cord injury (SCI) centers in Finland responsible for acute care, immediate rehabilitation, and lifelong follow-up for all SCI patients in a population of 3,073,052 (as of 2013).

PARTICIPANTS

All newly diagnosed NTSCI patients (N=430) admitted to Tampere University Hospital between 2012 and 2015 and Oulu University Hospital between 2013 and 2016 based on the evaluation of the designated rehabilitation teams. Patients with NTSCI resulting from congenital etiologies or progressive neurologic diseases were excluded.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Incidence and variables, according to the International SCI Core Data Set and the International Standards for Neurological Classification of SCI, including etiology and the severity of injury.

RESULTS

The incidence of NTSCI was 54.1 per million per year. NTSCI was more common in men (n=260, 60.5%) than women (n=170, 39.5%). The mean age was 62.0±14.6 years old. Degenerative causes were the most common etiology (n=219, 50.9%), followed by malignant (n=88, 20.5%) and benign (n=41, 9.5%) neoplasms. The injury resulted in tetraplegia in 177 patients (41.1%) and paraplegia in 249 patients (57.9%). American Spinal Injury Association Impairment Scale grade D injuries were common, with an incidence of 71% (n=304). Specialized inpatient rehabilitation was needed in 44% (n=189) of the cases.

CONCLUSIONS

There are no previous studies on the epidemiology of NTSCI in Finland, and international reporting has been limited. The incidence of NTSCI in our study was substantially higher than in most previous studies, which was likely owing to our study including individuals with less severe lesions who did not require inpatient rehabilitation.

Preliminary steps of the development of a Minimum Uniform Dataset applicable to the international wheelchair sector

Assistive products outcomes are needed globally to inform policy, practice, and drive investment. The International Society of Wheelchair Professionals developed a Minimum Uniform Dataset (MUD) for wheelchair services worldwide with the intent to gather data that is comparable globally. The MUD was developed with the participation of members from around the globe and its feasibility piloted at 3 sites. Three versions of the MUD are now available—a short form with 29 data points (available in English, Spanish, and French) and a standard version with 38 data points in English. Future work is to validate and complete the translation cycles followed by promoting the use of the MUD globally so that the data can be leveraged to inform policy, practice and direct investments.

Sexual abuse in people with spinal cord damage

Objectives: There are few studies of sexual abuse in people with spinal cord damage (SCD). Objective of this study was to determine the prevalence and impact of sexual abuse in SCD. Design: Survey (web and paper-based). Setting: Australia (August 2013-June 2014). Participants: People with SCD (n = 136); able-bodied controls (n = 220). Interventions: None. Outcome measures: Spinal Cord Injury Secondary Conditions Scale, International SCI Quality of Life Basic Dataset, and the Physical Disability Sexual and Body Esteem scale. Questions regarding demographic and clinical characteristics, sex, sexual orientation, relationship status, disability, sexual interest and satisfaction, and sexual abuse. Results: Most SCD participants were male (n = 92, 67%), the average age was 46 years (SD = 14) and they were median of 11 years (IQR 4-21) after SCD. Of these, 19% (n = 26) reported sexual abuse. Females were much more likely to report being abused (odds ratio 3.3, 95%CI 1.5-7.4; χ²=10.9, P = 0.001). Participants reporting sexual abuse were younger (P = 0.01) and more likely to have been abused before their SCD (69%). There was no significant difference between those with SCD who reported sexual abuse and those who did not regarding their quality of life as a whole (P > 0.1). There was no difference regarding the reporting of sexual abuse between able-bodied and those with SCD (P = 0.1). Conclusion: Sexual abuse was relatively common and was not associated with an adverse relationship with the covariates assessed. Further research is needed to better determine the prevalence of sexual abuse in people with SCD and its impact.

Utilization of Outpatient Physical and Occupational Therapy in People With Spinal Cord Injury in Germany: Results of the German Spinal Cord Injury Survey

OBJECTIVE

The aim of the study was to assess factors determining the utilization of physical and occupational therapy in people with spinal cord injury.

DESIGN

Data from the German Spinal Cord Injury study conducted in 2017 were analyzed. The 12-mo prevalence of physical therapy and occupational therapy utilization was determined. To identify underlying determinants, multivariable logistic regression was used.

RESULTS

Of 1479 participants (response = 26.4%), 72.9% were male, with a mean (SD) age of 55.3 (14.6) yrs and a mean (SD) time since injury of 14.0 (12.0) yrs; 51.2% were people with paraplegia and 66.3% had an incomplete spinal cord injury. In the past 12 mos, 78.1% received physical and 29.3% occupational therapy. Physical therapy and occupational therapy were significantly associated with time since spinal cord injury occurrence, participation in lifelong care programs, and electric wheelchair dependency. Spinal cord injury characteristics, level of impairment, and time since spinal cord injury had a greater impact on occupational therapy than on physical therapy utilization.

CONCLUSIONS

The use of physical therapy and occupational therapy is much higher in Germans with spinal cord injury than in the general population and in people with similar neurological conditions. Further research should focus on the frequency of use and the types of interventions. Guidelines for lifelong care should include recommendations on physical therapy and occupational therapy.

Utilizing three dimensional clinical gait analysis to optimize mobility outcomes in incomplete spinal cord damage

BACKGROUND

Three-dimensional gait analysis (3DGA) has not previously been considered by consensus panels of spinal cord experts for use in studies of patients with spinal cord damage (SCD), yet it is frequently used in other neurological populations, such as stroke and cerebral palsy.

RESEARCH QUESTION

How does 3DGA impairment based reporting guide individualised clinical decision-making in people with incomplete SCD?

METHODS

Retrospective open cohort case series recruited 48 adults with incomplete SCD (traumatic or non-traumatic spinal cord dysfunction) referred to the Clinical Gait Analysis Service (CGAS), Melbourne, Australia. Three-dimensional gait data were used to identify gait impairments by the multidisciplinary clinical team. Gait patterns were classified using the plantarflexor-knee extension couple index and the Gait Profile Score (GPS). The reason for referral and the recommendations made post-3DGA were collated in decision trees to extrapolate the potential value of 3DGA in decision making for targeted intervention in this population.

RESULTS

Participants with SCD generally walked at a reduced gait speed. When grouped by neurological level, the tetraplegia group had a significantly lower GPS, but no specific gait patterns emerged. Participants were primarily referred to the CGAS to direct clinical intervention decisions. The most frequent recommendation following 3DGA was the prescription of an ankle foot orthosis and in some cases, the recommendation was incongruent with the referrer's proposed intervention.

SIGNIFICANCE

3DGA can provide specific guidance in management plans for gait of patients with incomplete SCD and may help to avoid inappropriate or unnecessary interventions. This sample of patients referred to the CGAS demonstrates its clinical utility in guiding clinicians in their decision making to target individualised intervention.

Traumatic Spinal Cord Injuries with Fractures in a Québec Level I Trauma Center

BACKGROUND

Traumatic spinal cord injuries (TSCI) have devastating consequences on patients' quality of life. More specifically, TSCI with spinal fractures (TSCIF) have the most severe neurological impairment, although limited data are available. This study aimed at providing data and analyzing TSCIF in a level I trauma center in the province of Québec, Canada.

METHODS

Two hundred eighty-two TSCIF were reviewed. Spinal injuries and neurological impairment were assessed with AO classification and AIS, respectively. Variables included age, sex, cause, location, mechanism of injury (MOI), and severity of TSCIF. Chi-squared Pearson determined significant associations (p < 0.05).

RESULTS

Male-to-female ratio was 3.21:1. Patients were 42.5 ± 18.7 years. The leading causes of TSCIF were high-energy falls (28.4%), cars (26.2%) and vehicle without restraint system (motorcycle, all-terrain vehicle, snowmobile, and bicycle) (21.3%). Vehicle collisions, pooling cars and unrestrained vehicles, mostly affected the 20-49-year population (62.2%). The main MOI was distraction in males (47.9%), and axial compression in females (44.8%). There were significant associations between causes and injured spinal level, as well as between MOI and injured spinal level, sex, and TSCIF severity. Most patients involved in unrestrained vehicle accidents sustained a thoracolumbar spine distraction with complete motor deficit. A severe neurologic deficit affected most patients following car accidents that caused cervical spine distraction or axial torsion.

CONCLUSIONS

In Québec, most TSCIF caused by vehicle collisions affect a young population and have severe neurological impairments. Future efforts should focus on better understanding accidents involving the unrestrained vehicle category to further improve preventive measures.

A scoping review of peer-led interventions following spinal cord injury

STUDY DESIGN

Scoping review.

OBJECTIVES

The objective of this study is to report on the extent, range and nature of the research evaluating peer-led interventions following spinal cord injury, and to categorize and report information according to study design, peer role, intervention type and intended outcomes.

METHODS

Arksey and O'Malley's methodological framework for conducting scoping reviews was used. Original research studies of a peer-led intervention published between 2010 and present were included. CINAHL Plus, Ovid MEDLINE and PsycINFO were searched using key terms, in addition to citation checks. Data were extracted against a previously published consolidated typology.

RESULTS

Significant heterogeneity in studies (n = 21) existed in aims and methods. Two studies reported on randomized controlled trials with relatively robust sample sizes and qualitative methodology was common. Peer role was frequently described as 'peer support', but there was variation in the description and duration of the interventions, complicating the categorization process. The majority of interventions were conducted one to one (n = 15). Studies most commonly aimed to address community integration (n = 15) and health self-management outcomes (n = 10).

CONCLUSIONS

A small number of studies were eligible for review, although increasingly with rigorous designs. The nature of the peer mentor and mentee experiences were explored, and the interaction between the two, offering rich insights to the value of lived experience. Further work refining typology describing intervention type, peer roles and outcomes would facilitate replication of programmes and study designs, enabling statistical synthesis and potentially strengthening the credibility of peers as a viable resource in in-patient and community settings.

Satisfaction with life, health and well-being: comparison between non-traumatic spinal cord dysfunction, traumatic spinal cord injury and Australian norms

Study design

Cross-sectional survey.

Objectives

The objective of this study is to compare self-reported satisfaction with life, and self-reported health and well-being of people with NTSCD, to that of people with TSCI, and with Australian population.

Setting

Victoria, Australia.

Methods

Participants completed surveys by post or email. The Satisfaction with Life Scale (SWLS) and the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36) were used to assess self-reported satisfaction with life, and health and well-being. Descriptive statistics are reported including median and interquartile range (IQR). The Mann-Whitney U-test was used to investigate differences between groups.

Results

There were 41 participants: NTSCD (n = 14) and TSCI (n = 27). There were no significant differences in the median scores on the SWLS for NTSCD and TSCI, but both groups scored lower than the Australian non-disabled sample mean. There were significant differences between NTSCD and TSCI for SF-36 domains physical functioning, role limitations physical and vitality (p < 0.05). Median scores for both groups in all eight domains were lower than the means of the comparative Australian sample, except for role limitations emotional.

Conclusions

There were more apparent difficulties for people with NTSCD in completing desired functional tasks than those with TSCI. Both groups had lower self-reported satisfaction with life, and lower reported health and well-being in comparison to samples of non-disabled Australians.

Important Clinical Rehabilitation Principles Unique to People with Non-traumatic Spinal Cord Dysfunction

Background: Non-traumatic spinal cord dysfunction (SCDys) is caused by a large range of heterogeneous etiologies. Although most aspects of rehabilitation for traumatic spinal cord injury and SCDys are the same, people with SCDys have some unique rehabilitation issues. Purpose: This article presents an overview of important clinical rehabilitation principles unique to SCDys. Methods: Electronic literature search conducted (January 2017) using MEDLINE and Embase (1990-2016) databases for publications regarding SCDys. The focus of the literature search was on identifying publications that present suggestions regarding the clinical rehabilitation of SCDys. Results: The electronic search of MEDLINE and Embase identified no relevant publications, and the publications included were from the authors' libraries. A number of important clinical rehabilitation principles unique to people with SCDys were identified, including classification issues, general rehabilitation issues, etiology-specific issues, and a role for the rehabilitation physician as a diagnostic clinician. The classification issues were regarding the etiology of SCDys and the International Standards for Neurological Classification of Spinal Cord Injury. The general rehabilitation issues were predicting survival, improvement, and rehabilitation outcomes; admission to spinal rehabilitation units, including selection decision issues; participation in rehabilitation; and secondary health conditions. The etiology-specific issues were for SCDys due to spinal cord degeneration, tumors, and infections. Conclusions: Although there are special considerations regarding the rehabilitation of people with SCDys, such as the potential for progression of the underlying condition, functional improvement is typically significant with adequate planning of rehabilitation programs and special attention regarding the clinical condition of patients with SCDys.

Trends, Challenges, and Opportunities Regarding Research in Non-traumatic Spinal Cord Dysfunction

Background: Spinal cord dysfunction (SCDys) is caused by heterogeneous health conditions, and the incidence is increasing. Despite the growing interest in rehabilitation research for SCDys, research into SCDys faces many challenges. Objective: The objective of this project was to perform a clinical review of changes in SCDys research over the last 4 decades; identify challenges to conducting research in SCDys; and propose opportunities for improving research in SCDys. Methods: A triangulation approach was used for obtaining evidence: literature search (January 2017) using MEDLINE and Embase databases for publications in English (1974-2016) regarding SCDys; workshop discussions at the International Spinal Cord Society annual meeting, September 16, 2016, Vienna, Austria; and our collective expertise in SCDys clinical rehabilitation research. Results: There has been a substantial increase in publications on SCDys over the 4 decades, from 1,825 in 1974-1983 to 11,887 in the decade 2004-2013, along with an improvement in research methodology. Numerous challenges to research in SCDys rehabilitation were grouped into the following themes: (a) identification of cases; (b) study design and data collection; and (c) funding, preclinical, and international research. Opportunities for addressing these were identified. Conclusions: The increase in scientific publications on SCDys highlights the importance of this heterogeneous group among the research community. The overall lack of good quality epidemiological studies regarding incidence, prevalence, and survival in these patients serves as a benchmark for guiding improvements to inform evidence-based care and policy.

Age-specific characterization of spinal cord injuries over a 19-year period at a Japanese rehabilitation center

Regional demographics of spinal cord injuries (SCIs) are fundamental to identifying and implementing appropriate preventive measures. The current study was conducted as a longitudinal analysis of all patients with SCIs admitted to the Hyogo Rehabilitation Center over a 19-year period. The sex and age of the patient, time and nature of injury (i.e., cause, level, and extent), and period from injury to admission were evaluated retrospectively. Pertinent tests, including Poisson regression analysis, and the Cochran–Armitage, Kruskal–Wallis, and chi-square tests, were applied to assess demographic variables, with statistical significance set at p < 0.05. Between 1995 and 2013, a total of 632 patients with SCIs (predominantly male and largely < 60 years old) were admitted to our center for rehabilitation. Although the male: female ratio remained unchanged throughout the study period, the ratio of older adults increased over time. In assessing the cause of injury, the majority of the patients involved in road traffic accidents were aged ≤ 44 years, whereas patients aged ≥ 45 years accounted for the majority of low-distance falls and disease-related SCIs, the proportions of which gradually increased. Complete paralysis and paraplegia primarily occurred in patients aged ≤ 44 years, whereas the majority of incomplete injuries and tetraplegia were limited to those aged ≥ 45 years. The patient age at the time of SCI and the nature of the injury sustained were interrelated. Age-specific strategies thus offered the best means of preventing/reducing the incidence of SCIs in Hyogo prefecture.

Polypharmacy and adverse drug events among propensity score matched privately insured persons with and without spinal cord injury

STUDY DESIGN

Retrospective quasi-experimental design.

OBJECTIVES

To compare the incidence of adverse drug events (ADEs) between persons with and without spinal cord injury (SCI), while controlling for all potential and available risk factors.

SETTING

A commercially available claims dataset consisting of ~170 million patient cases in the United States between 2012 and 2013.

METHODS

Participants (aged 18-64 years) included 2779 persons with polypharmacy and traumatic or non-traumatic SCI and 2779 propensity score-matched persons with polypharmacy without SCI. The cohorts were matched using demographic variables including number of concomitant prescriptions, comorbidities, hospital admissions, age, gender, and geographic region. Inpatient and outpatient claims records containing 395 distinct IDC-9 codes indicative of ADEs were extracted. Incidence and frequency of ADEs were compared between groups using logistic and Poisson regression, respectively.

RESULTS

Persons with SCI were significantly more likely to experience an ADE than matched controls (Odds Ratio = 1.45, p < 0.0001). Among persons with ADEs (n = 1552), individuals with SCI experienced fewer ADEs over time than matched controls (Incidence Rate Ratio = 0.91, p < 0.0001).

CONCLUSIONS

While persons with SCI and polypharmacy are at a greater risk for experiencing an ADE, their medical care after an ADE may be better managed than that of a matched control population. There may be a need for practice guidelines that facilitate proactive identification of persons with SCI at the highest risk of ADE. Steps may then be taken to mitigate risk, in contrast to current practice trends that appear to take a reactive approach after an ADE has occurred.

Trunk Function and Ischial Pressure Offloading in Individuals with Spinal Cord Injury

OBJECTIVE

To determine if there is a relationship between trunk function and offloading of the ischial tuberosities in individuals with Spinal Cord Injury (SCI).

DESIGN

Prospective cross-sectional evaluation.

SETTING

Sub-acute rehabilitation hospital.

PARTICIPANTS

Fifteen non-ambulatory participants with complete or incomplete traumatic and non-traumatic SCI, American Spinal Injury Association Impairment Scale (AIS), Classification A-D.

OUTCOME MEASURES

Isometric trunk strength using a hand held dynamometer, the ability to reach using the multidirectional reach test and offloading times of the ischial tuberosities using a customized pressure mat.

RESULTS

Participants who were able to engage in the multidirectional reach test were defined as "Reachers", whereas individuals who were unable to engage in the multidirectional reach test were defined as "Non-Reachers". Trunk strength was significantly higher in Reachers compared with Non-Reachers (P < 0.05). Offloading times over the left and right ischial tuberosities were lower in Non-Reachers when compared with Reachers, however the results were statistically significant only for offloading over the right ischial tuberosity (P < 0.05). There was no correlation between trunk strength and pressure offloading times for both groups.

CONCLUSIONS

Regardless of an individual's ability to engage in a reaching task, participants with spinal cord injury spent more time offloading the left ischial tuberosity compared with the right ischial tuberosity. The study highlights the need to identify factors that may contribute to offloading behavior in individuals with spinal cord injury who lack sufficient trunk strength.

Understanding the factors that influence social and community participation as perceived by people with non-traumatic spinal cord injury

Introduction

The number of people with non-traumatic spinal cord injury is rising in developed countries such as Australia and Great Britain. People with non-traumatic spinal cord have different gender, injury and age-related profiles compared to those with traumatically acquired spinal cord injury; therefore, their lived experience is likely to be different. However, the specific issues and challenges that this group faces have not been well investigated.

Method

Semi-structured in-depth interviews were conducted with 17 adults with non-traumatic spinal cord injury. Interviews were audio-recorded, transcribed verbatim and analysed using thematic analysis.

Findings

The factors that influenced the social and community participation of people with non-traumatic spinal cord injury were grouped into three broad areas: person factors, factors in the physical and institutional environment, and factors in the social or cultural environment.

Conclusion

The findings from this study inform the understanding of occupational therapists regarding the social and community participation of people with non-traumatic spinal cord injury and how this can be facilitated. Assisting people with non-traumatic spinal cord injury to participate in meaningful social and community-based activities is important to maximise their quality of life.

Rehabilitation of people with spinal cord damage due to tumor: literature review, international survey and practical recommendations for optimizing their rehabilitation

BACKGROUND/OBJECTIVES

People with spinal cord dysfunction (SCDys) due to tumor (benign and malignant) pose enormous rehabilitation challenges. Objectives were: conduct literature search regarding epidemiology, clinical features and outcomes for SCDys due to tumor following rehabilitation, the ideal setting for rehabilitation and practical considerations for rehabilitation; and propose framework and practical considerations for managing people with SCDys due to tumor in spinal rehabilitation units (SRUs).

DESIGN

Survey of rehabilitation health care professionals, consensus opinion from experts and literature search.

SETTING

Workshop at International Spinal Cord Society and American Spinal Injury Association combined annual meeting, May 16, 2015, Montréal, Canada.

PARTICIPANTS

Workshop attendees and experts in the rehabilitation of people with SCDys due to tumor.

OUTCOMES MEASURES

Reports of services offered to people with SCDys due to tumor, including whether those with benign and malignant tumors are admitted into rehabilitation, any admission criteria used and the rational for declining admission.

RESULTS

Most respondents (n = 33, 83%) reported that people with benign tumors were routinely admitted for rehabilitation but only 18 (45%) reported that people with malignant tumors were routinely admitted. A range of criteria and reasons for declining admission were given. Evidence from the literature and the opinion of experts support the admission of people with SCDys due to tumor into specialist SRUs.

CONCLUSIONS

A framework and practical considerations for managing people with SCDys due to tumor in SRUs are proposed. Patients with tumor causing SCDys should be given greater access to specialist SRU in order to achieve the best outcomes.

Creation of an Algorithm to Identify Non-traumatic Spinal Cord Dysfunction Patients in Canada Using Administrative Health Data

Background: The lack of consensus on the best methodology for identifying cases of non-traumatic spinal cord dysfunction (NTSCD) in administrative health data limits the ability to determine the burden of disease and provide evidence-informed services. Objective: The purpose of this study is to develop an algorithm for identifying cases of NTSCD with Canadian health administrative databases using a case-based approach. Method: Data were provided by the Canadian Institute for Health Information that included all acute care hospital and day surgery (Discharge Abstract Database), ambulatory (National Ambulatory Care Reporting System), and inpatient rehabilitation records (National Rehabilitation Reporting System) of patients with neurological impairment (paraplegia, tetraplegia, and cauda equina syndrome) between April 1, 2004 and March 31, 2011. The approach to identify cases of NTSCD involved using a combination of diagnostic codes for neurological impairment and NTSCD etiology. Results: Of the initial cohort of 23,703 patients with neurological impairment, we classified 6,362 as the "most likely NTSCD" group (had a most responsible diagnosis or pre-existing diagnosis of NTSCD and diagnosis of neurological impairment); 2,777 as "probable NTSCD" defined as having a secondary diagnosis of NTSCD, and 11,179 as "possible NTSCD" who had no NTSCD etiology diagnoses but neurological impairment codes. Conclusion: The proposed algorithm identifies an inpatient NTSCD cohort that is limited to patients with significant paralysis. This feasibility study is the first in a series of 3 that has the potential to inform future research initiatives to accurately determine the incidence and prevalence of NTSCD.

Prevalence and associated factors of pain in the Swiss spinal cord injury population

STUDY DESIGN

Population-based, cross-sectional.

OBJECTIVES

To determine pain prevalence and identify factors associated with chronic pain in individuals with spinal cord injury (SCI) living in Switzerland.

SETTING

Swiss SCI Cohort Study (SwiSCI).

METHODS

Pain characteristics were assessed using an adapted version of the International SCI Pain Basic Data Set, adding one item of the SCI Secondary Conditions Scale to address chronic pain. Pain prevalence was calculated using stratification over demographic, SCI-related and socioeconomic characteristics; odds ratios (adjusted for non-response) for determinants of severity of chronic pain were calculated using stereotype logistic regressions.

RESULTS

Pain (in the past week) was reported by 68.9% and chronic pain by 73.5% (significant 36.9%) of all participants (N=1549; 28% female). Most frequently reported pain type was musculoskeletal (71.1%). Back/spine was the most frequently reported pain location (54.6%). Contrasting the 'significant' to the 'none/mild' category of chronic pain, adjusted odds ratios were 1.54 (95% CI: 1.18-2.01; P<0.01) for women (vs men); 6.64 (95% CI: 3.37-11.67; P<0.001) for the oldest age group 61+ (vs youngest (16-30)); 3.41 (95% CI: 2.07-5.62; P<0.001) in individuals reporting severe financial hardship (vs no financial hardship). Individuals reporting specific SCI-related health conditions were 1.41-2.92 (P<0.05) times more likely to report chronic pain as 'significant' rather than 'none/mild' compared with those without the respective condition.

CONCLUSIONS

Pain is highly prevalent in individuals with SCI living in Switzerland. Considered at risk for chronic pain are women, older individuals and individuals with financial hardship and specific secondary health conditions. Longitudinal studies are necessary to identify predictors for the development of pain and its chronification.

Secondary conditions in a community sample of people with spinal cord damage

OBJECTIVE

To compare secondary conditions in people with traumatic spinal cord injury (SCI) and non-traumatic spinal cord dysfunction (SCDys).

DESIGN

Survey; completed August 2012 - June 2013.

SETTING

Community, Australia.

PARTICIPANTS

Adults with spinal cord damage from any cause.

INTERVENTIONS

Nil.

OUTCOME MEASURES

Demographic and clinical variables and the SCI-Secondary Conditions Scale (SCI-SCS).

RESULTS

Survey completed by 150 people: 112 (74.7%) with traumatic SCI and 38 (25.3%) with non-traumatic SCDys a median of 10 years post onset. No significant difference (t = -0.6, P = 0.6) in the total SCI-SCS score between those with SCI (mean 13.7) and SCDys (mean 14.4). Except for bladder problems (SCDys mean = 1.5, SD = 1.1; SCI mean = 1.0, SD=1.1; t = -2.6, P = 0.01) there were no significant differences between the aetiology groups regarding the conditions comprising the SCI-SCS (all other P values >0.1). The most common significant or chronic problems from the SCI-SCS were: sexual problems 41%; chronic pain 24%; bladder dysfunction 17%; spasms 17%; joint and muscle pain 15%; bowel dysfunction 14%; circulation problems 14%; contractures 9%; urinary tract infections 9%; pressure ulcer 7% and postural hypotension 5%. A linear regression analysis found that tetraplegia and higher disability were the only variables that significantly influenced (R² = 0.13; P = 0.005) the total SCI-SCS score and that sex, age, years post injury and etiology of spinal cord damage had no influence.

CONCLUSIONS

Secondary conditions following spinal cord damage do not appear to be influenced by etiology. Prevention and management of secondary conditions following need to consider people with non-traumatic SCDys as well as those with traumatic SCI.

Impact of voice and communication deficits for individuals with cervical spinal cord injury living in the community

BACKGROUND

Post-spinal cord injury (SCI), individuals may exhibit mild to moderate impairments in aspects of speech influenced by impaired respiratory support. However, limited research has been conducted into the impact of these impairments on activity and participation when living in the community.

AIMS

To examine the nature and extent of voice and communication function in a group of individuals with cervical SCI living in the community, and to explore participant perceptions of the impact of these deficits on levels of activity and participation.

METHODS & PROCEDURES

Participants included 14 individuals who had sustained a SCI above C8 level and had returned to living in the community. All completed a series of speech and voice assessments, the Voice Handicap Index, the Australian Therapy Outcome Measures Voice scale, four voice perception questions, and the General Short Form of the Communicative Participation Item Bank.

OUTCOMES & RESULTS

As a group, participants were found to have reduced vocal intensity and phonatory duration. Vocal quality was mildly altered in 93% and pitch control, breath support for speech, speech rate and phrase length impacted in one-quarter or more of the group. All reported impacts, though three individuals reported that their impairments had more extensive impact on communication in daily life.

CONCLUSIONS & IMPLICATIONS

Individuals post-SCI experience mild speech and voice deficits that can have negative impacts on functional communication. The monitoring of communication function may help to identify those individuals who could benefit from additional support and intervention on return to community life.

Prevalence of mood disturbance in Australian adults with chronic spinal cord injury

BACKGROUND

There is little understanding of the prevalence of mental health issues in people with spinal cord injury (SCI) after they leave rehabilitation or how mental health issues can alter over time.

AIM

The aims were to (i) determine the prevalence of mood disturbance in adults with chronic SCI living in the community, (ii) ascertain whether the prevalence of mood disturbance had changed since a previous study in 2004-2005 and (iii) establish whether people with chronic SCI remain vulnerable to mood disturbance, irrespective of time since injury.

METHODS

Prospective, open-cohort case series. Participants were 573 community-based adults with a chronic SCI. The depression, anxiety and stress scale - short version was used. Analyses included simple descriptors, Chi-squared and repeated measures t-tests.

RESULTS

Nearly half of participants (n = 263/573; 46%) reported symptoms indicating mood disturbance, which was similar to the level found in the previous study. While the presence of mood disturbance persisted in 23% of adults (n = 26) and 46 (41%) were in the 'below threshold' category, just over a third of the adults who participated in both studies (n = 111) experienced a change (n = 21, 19% mood disturbance resolved and n = 18, 16% mood disturbance developed).

CONCLUSION

Both resilience and change are common. At no time after SCI is the risk of mental health problems considered reduced or even stable. These results highlight the importance of regular mental health reviews even in those who have previously displayed good resilience.

Nontraumatic spinal cord injury at the neurological intensive care unit: spectrum, causes of admission and predictors of mortality

OBJECTIVE

Nontraumatic spinal cord injuries (NTSCIs) form a heterogeneous group of diseases, which may evolve into a life-threatening condition. We sought to characterize spectrum, causes of admission and predictors of death in patients with NTSCI treated at the neurological intensive care unit (NICU).

METHODS

We performed a retrospective observational analysis of NTSCI cases treated at a tertiary care center between 2001 and 2013. Among the 3937 NICU admissions were 93 patients with NTSCI (2.4%). Using multivariate logistic regression analysis, we examined predictors of mortality including demographics, etiology, reasons for admission and GCS/SAPS (Glasgow Coma Scale/Simplified Acute Physiology Score) scores.

RESULTS

Infectious and inflammatory/autoimmune causes made up 50% of the NTSCI cases. The most common reasons for NICU admission were rapidly progressing paresis (49.5%) and abundance of respiratory insufficiency (26.9%). The mortality rate was 22.6% and 2.5-fold higher than in the cohort of all other patients treated at the NICU. Respiratory insufficiency as the reason for NICU admission [odds ratio (OR) 4.97, 95% confidence interval (CI) 1.38-17.9; p < 0.01], high initial SAPS scores (OR 1.04; 95% CI 1.003-1.08; p = 0.04), and the development of acute kidney injury throughout the stay (OR 7.25, 1.9-27.5; p = 0.004) were independent risk factors for NICU death.

CONCLUSIONS

Patients with NTSCI account for a subset of patients admitted to the NICU and are at risk for adverse outcome. A better understanding of predisposing conditions and further knowledge of management of critically ill patients with NTSCI is mandatory.

Gait speed using powered robotic exoskeletons after spinal cord injury: a systematic review and correlational study

Powered robotic exoskeletons are an emerging technology of wearable orthoses that can be used as an assistive device to enable non-ambulatory individuals with spinal cord injury (SCI) to walk, or as a rehabilitation tool to improve walking ability in ambulatory individuals with SCI. No studies to date have systematically reviewed the literature on the efficacy of powered exoskeletons on restoring walking function. Our objective was to systematically review the literature to determine the gait speed attained by individuals with SCI when using a powered exoskeleton to walk, factors influencing this speed, and characteristics of studies involving a powered exoskeleton (e.g. inclusion criteria, screening, and training processes). A systematic search in computerized databases was conducted to identify articles that reported on walking outcomes when using a powered exoskeleton. Individual gait speed data from each study was extracted. Pearson correlations were performed between gait speed and 1) age, 2) years post-injury, 3) injury level, and 4) number of training sessions. Fifteen articles met inclusion criteria, 14 of which investigated the powered exoskeleton as an assistive device for non-ambulatory individuals and one which used it as a training intervention for ambulatory individuals with SCI. The mean gait speed attained by non-ambulatory participants (n = 84) while wearing a powered exoskeleton was 0.26 m/s, with the majority having a thoracic-level motor-complete injury. Twelve articles reported individual data for the non-ambulatory participants, from which a positive correlation was found between gait speed and 1) age (r = 0.27, 95 % CI 0.02-0.48, p = 0.03, 63 participants), 2) injury level (r = 0.27, 95 % CI 0.02-0.48, p = 0.03, 63 participants), and 3) training sessions (r = 0.41, 95 % CI 0.16-0.61, p = 0.002, 55 participants). In conclusion, powered exoskeletons can provide non-ambulatory individuals with thoracic-level motor-complete SCI the ability to walk at modest speeds. This speed is related to level of injury as well as training time.

Neurogenic Bladder and Urodynamic Outcomes in Patients with Spinal Cord Myelopathy

BACKGROUND

Urodynamics (UDs) are routine in traumatic spinal cord injury (SCI), but there are few reports regarding nontraumatic spinal cord myelopathy (SCM) patients.

PURPOSE

To describe the neurogenic bladder and UD outcomes in SCM patients and determine whether the UD recommendations result in clinically important changes to bladder management.

METHODS

This retrospective case study examined a series of SCM patients admitted to a spinal rehabilitation service who underwent UDs between January 1, 2000 and June 30, 2010.

RESULTS

Sixty-five UD tests were performed a median of 7 months post SCM. Most (n = 34; 57%) patients were male, and the median age was 60 years. Most patients (n = 46; 77%) were paraplegic and were continent of urine (n = 38; 58%). Thirty-five (46%) patients voided on sensation, 26 (40%) performed intermittent self-catheterization, and 9 (14%) had an indwelling catheter. The most common UD finding was overactive detrusor with no dysynergia (n = 31; 48%), followed by overactive detrusor with sphincter dysynergia (n = 16; 25%) and detrusor areflexia/underactive (n = 12; 18%). Key UD findings were median cystometric capacity 414 mL (interquartile range [IQR], 300-590), median maximum detrusor contraction 49.5 cmH2O (IQR, 25-85), and median residual volume post voiding 100 mL (IQR, 5-200). The recommendations for changes to bladder management following UDs resulted in clinically important changes to existing strategies in 57 studies (88%).

CONCLUSIONS

Future studies should ascertain whether our screening protocol is appropriate, and a longer-term follow-up should examine the relationship between UD recommendations and prevention of complications.

Comparison of Rehabilitation Outcomes for Long Term Neurological Conditions: A Cohort Analysis of the Australian Rehabilitation Outcomes Centre Dataset for Adults of Working Age

OBJECTIVE

To describe and compare outcomes from in-patient rehabilitation (IPR) in working-aged adults across different groups of long-term neurological conditions, as defined by the UK National Service Framework.

DESIGN

Analysis of a large Australian prospectively collected dataset for completed IPR episodes (n = 28,596) from 2003-2012.

METHODS

De-identified data for adults (16-65 years) with specified neurological impairment codes were extracted, cleaned and divided into 'Sudden-onset' conditions: (Stroke (n = 12527), brain injury (n = 7565), spinal cord injury (SCI) (n = 3753), Guillain-Barré syndrome (GBS) (n = 805)) and 'Progressive/stable' conditions (Progressive (n = 3750) and Cerebral palsy (n = 196)). Key outcomes included Functional Independence Measure (FIM) scores, length of stay (LOS), and discharge destination.

RESULTS

Mean LOS ranged from 21-57 days with significant group differences in gender, source of admission and discharge destination. All six groups showed significant change (p<0.001) between admission and discharge that was likely to be clinically important across a range of items. Significant between-group differences were observed for FIM Motor and Cognitive change scores (Kruskal-Wallis p<0.001), and item-by-item analysis confirmed distinct patterns for each of the six groups. SCI and GBS patients were generally at the ceiling of the cognitive subscale. The 'Progressive/stable' conditions made smaller improvements in FIM score than the 'Sudden-onset conditions', but also had shorter LOS.

CONCLUSION

All groups made gains in independence during admission, although pattern of change varied between conditions, and ceiling effects were observed in the FIM-cognitive subscale. Relative cost-efficiency between groups can only be indirectly inferred. Limitations of the current dataset are discussed, together with opportunities for expansion and further development.

Trunk strength and function using the multidirectional reach distance in individuals with non-traumatic spinal cord injury

CONTEXT

Trunk control is essential to engage in activities of daily living. Measuring trunk strength and function in persons with spinal cord injury (SCI) is difficult. Trunk function has not been studied in non-traumatic SCI (NTSCI).

OBJECTIVES

To characterize changes in trunk strength and seated functional reach in individuals with NTSCI during inpatient rehabilitation. To determine if trunk strength and seated reach differ between walkers and wheelchair users. To explore relationships between trunk and hip strength and seated functional reach.

DESIGN

Observational study.

SETTING

Two SCI rehabilitation facilities.

PARTICIPANTS

32 subacute inpatients (mean age 48.0 ± 15.4 years).

OUTCOME MEASURES

Isometric strength of trunk and hip and function (Multidirectional Reach Test: MDRT) were assessed at admission and within 2 weeks of discharge. Analysis of variance was conducted for admission measures (MDRT, hip and trunk strength) between walkers and wheelchair users. Changes in MDRT, hip and trunk strength were evaluated using parametric and non-parametric statistics. The level of association between changes in values of MRDT and strength was also examined.

RESULTS

Significant differences between walkers and wheelchair users were found for strength measures (P < 0.05) but not for MDRT. Left- and right-sided reaches increased in wheelchair users only (P < 0.05). Associations between changes in hip strength, trunk strength, and reach distance were found (R = 0.67-0.73).

CONCLUSION

In clinical settings, it is feasible and relevant to assess trunk, hip strength, and MRDT. Future studies require strategies to increase the number of participants assessed, in order to inform clinicians about relevant rehabilitation interventions.

Epidemiology of spinal cord injuries and risk factors for complete injuries in Guangdong, China: a retrospective study

Background

Spinal cord injuries are highly disabling and deadly injuries. Currently, few studies focus on non-traumatic spinal cord injuries, and there is little information regarding the risk factors for complete injuries. This study aims to describe the demographics and the injury characteristics for both traumatic and non-traumatic spinal cord injuries and to explore the risk factors for complete spinal cord injuries.

Methods

A retrospective study was performed by reviewing the medical records of 3,832 patients with spinal cord injuries who were first admitted to the sampled hospitals in Guangdong, China. The demographics and injury characteristics of the patients were described and compared between the different groups using the chi-square test. Logistic regression was conducted to analyze the risk factors for complete spinal cord injuries.

Results

The proportion of patients increased from 7.0% to 14.0% from 2003 to 2011. The male-to-female ratio was 3.0∶1. The major cause of spinal cord injuries was traffic accidents (21.7%). Many of the injured were workers (36.2%), peasants (22.8%), and unemployed people (13.9%); these occupations accounted for 72.9% of the total sample. A multivariate logistic regression model revealed that the OR (95% CI) for male gender compared to female gender was 1.25 (1.07–1.89), the OR (95%CI) for having a spinal fracture was 1.56 (1.35–2.60), the OR (95%CI) for having a thoracic injury was 1.23 (1.10–2.00), and the OR (95%CI) for having complications was 2.47 (1.96–3.13).

Conclusion

The proportion of males was higher than the proportion of females. Workers, peasants and the unemployed comprised the high-risk occupational categories. Male gender, having a spinal fracture, having a thoracic injury, and having complications were the major risk factors for a complete injury. We recommend that preventive measures should focus on high-risk populations, such as young males.
